AUTOMOBILE BUMPER.

Application filed April 29,

To all whom it may concern.

Be it known that I, EDWARD PARRADEE, a citizen of the United States, residing at Grand Rapids, in the county of Kent and State of Michigan, new and useful Im ,roveme'nts in Automobile-Bumpers, of which the following is a specification. ii

My invention relat s toimprovements in so called bumpers for use upon automobiles, and its objects are: first,to provide a two plate spring bumper with which the back plate will be continuous, and the front layer will be divided; second, to provide a means whereby the of the bumper cannot come in direct contact with each other, and, third, to provide a means whereby the approaching ends of the front layerwill be held rigid and perfectly safe from becoming detached from the strengthening elements.

I attain these objects by the mechanism and construction shown in the accompany ing drawing, in which Figure 1 is an elevation of the bumper disconnected from an automobile. Fig. 2 is a plan of the same with the clamping elements in place. Fig. 3 is the same with the upper piece of the clamping element removed to show the form of the edges of the strengthening or splicing plate. Fig. 4 is a perspective of the splicing plate. Fig. 5 is a transverse section of the bumper upon the line 5-5 of Fig. 1.

imilar numerals indicate similar parts throughout the several views.

In the construction of this bumper I make the bumper, proper, of :a single, plate of metal having the back layer 1 continuous with a curve tinued parallel with the back plate, as at 1, and the disconnected ends a short distance apart. I make the splicing plate of the same width as the bumper plate but short, and form an offset, as i, at each edge thereof that is designed to hold the ends of the front plate 1 of the bumper from being forced together.

I provide for rigidly and firmly tying the splicing plate together by the use ofduplicate top and bottom plates 3 having grooves in their adjacent faces for the reception of the edges of plates. as shown in Fig. I of said plates having grooves wide enough to'receive the ends of the front plate and the I Specification of Letters Patent.

splicing plate. These plates are held firmly clamped upon the bumper by means of 4c, substantially as shown in Figs. 1, 2 and 3.

6 represents the supporting arms by means of which the bumper is connected with the frame of an automobile, the manner of making such connections not being here shown as the same is in common use upon this class of bumpers, as is,'also', the manner of connecting the supporting arms with the bumpers, as indicated by the bolts 8 or the clamp ing staples 9, shown in Figs. 2 and 3.

It is to be understood that the body of this bumper, like all bumpersof its class, is to be made of-spring metal capable of with-i standing all. ordinary shocks Ithat may be brought to bear uponit, as the sudden stopping of an automobile ahead without time to properly stop the automobile following.

Vith this bumper I have achieved several advantageous features over other' similar types of bumpers, as follows: First, I dis pense with the necessi'yof punching, drilling or otherwise forming holes in the plates for securing the central strengthening elements; second, I provide a double spring plate bumper, the construction of which is as of a continuous, unbroken steel plate, thus greatly enhancing its resilient qualities without, in any way, detracting from its symmetry or the artistic features of its construction, and, third, I can place the supporting arms 6 at any point upon the back plate of the bumper, thus rendering it an easy matter to adjust the bumper to any style of automobile chassis. Thus, I am able to provide a stronger, more resilient and more readily adjusted bumper at much less expense than any other bumper of its class now on the market.

What I claim as new in the art, is:

1. In a bumper for automobiles, a body made of flat spring metal plate bent to form loops at the ends. the back plate made continuous and the front plate divided at its longitudinal center and the ends spaced apart, the front plate and the back plate and loops equally spaced apart, a splicing plate having its edges oflset at its longitlulinal center to pass between the ends of the front plate, and means for securely connecting the splicing plate with the front plate and holding all rigidly connected.

2. In a bumper for automobiles. a body formed of a single spring metal plate bent bolts and to space a front plate to term a loop at each end of the bumper and a back plate an equal distance apart the entire length of the bumper, the .l'ront plate divided at its loi'igitudinal center and the ends spaced apart, a sl'ilicinpplate having the edges offset at its longitudinal center to pass intothe space between the ends of the front plate, an upper plate anda lower plate having, a groove in one side at one edge to pass over the edge of the back plate, and a groove at the other edge to pass over theends (it the front plate and the splicing plate, and bolts passed through said upper and lower plates securing them lirnily upon the edges of the back plate, the front plate and the splicing Leasws plate, and means l'or securing the bumper to an automobile.

3. In a bumper for automobiles, a body formed of a single springmetal plate bent to form a. loop at each end and a front plate and a back plate equally spaced apart, the back plate continuous and the front plate divided at its longitudinal center and the ends spaced apart, means for securely connecting and firmly splicing the divided front plate, and securing arms secured to the back plate and longitudinally Signed at Grand Rapids, l\"lichigan, April 24, 1920.
